Popis:	Diacylglyceryl-N,N,N-trimethylhomoserine (DGTS) belongs to a family of three known betaine lipids. It is synthesized by a number of bacteria, fungi, brown, red and green algae, in addition to lichens, and is also found in higher plants Bryophyta, Equisetophyta and Polydiophyta. It has been determined that DGTS plants can be DGTS-positive or DGTS-negative. The purpose of the present study was to examine the leaves of the ferns Drytopteris filix-mas (L.) Tod. and Pteridium aquilinum (L.) Kuhn, collected at different time periods during a single vegetation season for their DGTS contents. The results obtained show that amounts of DGTS in all of the species examined varies relative to the time periods in which they were collected.
